When mapping digital footprints, security analysts and open-source intelligence (OSINT) practitioners rely heavily on registration checkers. For years, single-purpose utilities like Holehe were the industry standard for checking email recovery endpoints. However, modern target profiling requires deeper correlation, higher concurrency, and cross-platform pivoting across both emails and usernames.
Enter user-scanner—a high-throughput, 2-in-1 Python OSINT engine designed for deep email registration checking, username profiling, and cross-scan intelligence.
